[Elecraft] PX3: Apparent "bug" fw 1.42

[wickedbeernut]

Holding the MENU / LABELS switch toggles between 0 (FN key labels off), 1 (FN
key labels on) and 2 (text decode on).

Tapping the DISP / AVERAGE switch toggles between 0 (spectrum only) and 1
(spectrum + waterfall).

With text decode off, the Waterfall window height range is 20 - 139.

With text decode on, the Waterfall window height range depends on the Text
menu / Txt Font,

  5x7:  20 - 130
7x11:  20 - 100
9x14:  20 - 80

I assume the Text menu / Waterfall value is read from the EEPROM into a
"local variable" at the time the PX3 is powered on.  With text decode on,
the Waterfall local variable is (potentially) "capped" based on the Text
menu / Txt Font.  Note:  This doesn't change the Text menu / Waterfall value
stored in the EEPROM.  For example, if the Text menu / Waterfall value is
139, Text menu / Txt Font is 7x11 and text decode is on,  the Waterfall
local variable is capped at 100.

You're pointing out that if text decode is turned off, the Text menu /
Waterfall value is not restored (i.e., not re-read from the EEPROM).

If you power the PX3 off and on, the Text menu / Waterfall value is re-read
from the EEPROM.  If text decode is off, the Waterfall local variable is not
capped.  The Waterfall local variable is 139.

Paul can address whether the Text menu / Waterfall value can be re-read from
the EEPROM in turning text decode off or possibly maintaining / deriving the
capped Waterfall local variable separately / independently.
